What this post added

This post introduces and details the practical application of the `temporal_cloud_v1_billable_action_count` metric. It provides specific PromQL queries for analyzing cost drivers by Workflow Type and Action Type, estimating total Actions over time, and setting up adaptive alerts for Action volume spikes. It also explains how this metric can be used for debugging workflow execution paths by identifying rare bugs and deployment regressions that add extra Actions.
